Hi again.  I am looking for an optical sensor, probably LED based,
maybe laser diode, that can be mounted on a thin PCB.  It needs to be
fairly small.  I am designing a small retroreflective system from
inside a slot machined into a molding with a piece of reflective tape
approx 3 ft away.

Any takers on this one?

How about a laser pointer. One you can buy at a dollar store.

All of the current production stuff will have receiver overloads (bury
the PIN photodiode) or will ignore a CW signal. Did stuff like that
15 years ago.
